To all whom it may concern: 7

Be it known that we, HERMAN KERNGOOD, residing at Baltimore city, State of Maryland, at New York city, county and State of ew York, citizens of the United States, have invented certain new and useful Improvements in Wheel-Tires for Automobiles, ofi which the following is a specification. I

Our invention relates to an improvement in wheel-tires; and-the object is [to decrease the liability of the tires to be cut! and aiiord' at the same time a yielding com iessible lateral internal support for the rub er tire.

With the foregoinggobjeCt in view our invention consists in certain novel pfeaturestof construction and combinations!" of parts which will be hereinafterde scribed, and pointed out in the claim.

In the accompanying'drawings, Figure -1. is a longitudinal section. Fig. 2 is a transverse section; and Fig. 3 is a section through one of ich the same is attached.

the spring-holding strips and the edge of the rim, to W A represents a metallic rim, more :or less the spokes:

oval in cross section, to which B is a convolute s rin This spring is made of comparative y t steel with its ends bent in s iral form ino'pposite directions,

the sprin has slidmg relation' between the rim and't e strips 1 1 of metal secured to the rim. The stri s 1 1 are held'removed from 3 rim and having loose sliding connection bethe rim a suita le distance by washers 2' 2 or similar means to permit the spring tomove freely in the space thus formed, screws 3 3 being employed to hold the strips securely in place. The parts of the spring preferably ereby' lateral support is afforded. As

engage eac'liother at the center, as shown at many of these sprin s are employed as may be required to afior s'u port for the rubber tire, and they may be p aced at suitable intervals a art for this purpose.

A steel strip 5, bent, transversely to. conform to the curvature of the springs, fits over the several springs, and the rubber tire 6 fits not wis over the spaceintervem; v s 'of the rim with which l around this steel strip and. the springs inclosing them and issecured at its edges in any 1 convenient manner to the ed es' of the rim.

From :the'foregoing it wil be seenythat a simple means lsjprovided' for supporting and sustaining. the weight applied upon the rublateral strain. and pressure resulting om 55 .ber tire, and-means isprovided for takin the sudden turns which throws the weight laterally upon the tirefat the "samestime'prev'enti undue wear and cutting of the tire; A va eel-rim of this character is elastic and resilient and instantly res onsive to compression and'strain and quic y resumes its nor-' mal condition upon theexcessive strain or pressure ,be ingremoved. Owing-to thepe-' culiarconstruction of the transverse con" 0- l'ute springs, there is no danger oftheir being collapsed or forced out: ofplace, as the parts going to make them up cooperate in action andtogether and unitedly' sustain all of the strain.

j Slight changes might be resorted to infl'the form. and arrangement of the several partsv described without departing from the spirit and scope of our invention, and hence we do to limit ourselves to the exact construction herein set forth; but,

Having fully described our invention,what I we claim as new, and desire to secure by Let-v ters Patent, is

The combination with" a sheet-metal rim,

strips securedto the rim with washers interosed between the strips and the rim, convo- I ute springs. extending transversely ofkthe tween the rims and the strips, a transverselybent strip '5 fitted-over the several springs and a rubber tire inclosing said strip and springs and securedatits edges in edges of' tures in the presence of two witnesses.
